PIN 1-8 power control
Please set the current of pump laser diode which is the output power through a combination of
TTL signals of PIN1~8. The encoding can be set within the range of 0~255 which is corresponding
to the 0~100% power output power (the actual optical power output may not be a linear
relationship with these settings). Please refer to the description in table 9:
